High quality green laser pointer
The high-quality green laser pointer is recommended for observing various situations, simple stars and constellations. This laser is particularly suitable for forward observation and display of celestial bodies, because green is the most sensitive color among all available red, blue, green and infrared laser pointers. Surprisingly compact but sturdy body with high quality. It is housed in an aluminum housing. Condenser tin wire, 12m match light, 10m 20m firecrackers, black plastic bags of cigarettes can be destroyed, black cloth can be cut, shock-resistant laser pointer/LED light-laser indication, and then turn on the LED in the dark, repel the crow laser flashlight is better than ordinary flashlights brighter. Be careful when using high power laser pointer in museums-because some paintings may be sensitive to light, laser pointers are not suitable for use. In the zoo---in order to avoid frightened animals, do not use laser pointers either. In recent years, products on the market have falsely reported the number of lumens. Calculating lumens requires special calculations and depends on the type and number of light sources used, the type and number of batteries used, and their amperage. Please pay attention to the representation of false lumens. This unretouched photo shows how the outdoor beam seems to end after a few hundred feet. This is a potentially dangerous illusion. The beam is actually moving all the time-even if the observer is scattered and cannot see the returning light. The beam can be dangerous to pilots from miles away, not hundreds of feet.I bought it. The specifications say it can reach 100 to 150 meters, but because there is no place to measure the distance, I tried it at the farthest place of my house (about 10 meters), and a clear red dot reflected on the wall. (*It will be difficult to see if exposed to direct sunlight indoors.)

Amateur astronomy-repelling the crow-refers to when using a laser pointer star, the star pointer is often used for a long time, so as not to interfere with the photography of other celestial bodies. You can use the recommended beam of a high-power laser pointer to point objects far enough, pop up black balloons, burn black matches, or cut electrical stripes. This more powerful green laser pointer is no longer a toy, but an entertainment tool, which should be kept out of the reach of children. It should be noted that do not refer to it. In crowded public places-you should stop using laser pointers to avoid hurting others. From the player's hand, the green laser pointer beam was shining in all directions, and the performance was unfolding. After pasting, it seemed that the laser beams were shot from the four fingertips other than the thumb, a total of eight left and right. It seems that the laser beam can be operated freely. I installed a powerful laser diode in my palm, which should be used by the club DJ, and created a laser glove that can emit light freely.It is fully used for marking (instruction) of construction sites such as walls and bridges on outdoor construction sites during the day and sunny days. In addition, at night, you can clearly see the green light from your hand to the celestial body, so you can use it in various ways according to your ideas, such as constellation observation.
